Thank you so much for your answer, I've been trying and testing some things and your suggestion of testing Isadora to Isadora was very useful. there seems to be an ndi compatibility issue between touchdesigner and Isadora or something. right now I'm using syphon on the Touch macbook to get the visuals into Isadora and using ndi to send it to the other computer.

So syphon Touch > Isadora gives smoother results than using NDI it seems.

Hope this helps others as well who run into this problem

i think the issue i'm having is related to this older post Re: [[ANSWERED] Refresh FPS and monitor / Stage Preview](/topic/6403/answered-refresh-fps-and-monitor-stage-preview) and am hoping it will be addressed when this bug is fixed?

I use 3 monitors in my control panels, all previewing results of some fairly fast movie clip cutting/mixing. Am using HAP encoded movies (vid-gpu), on a high-specd 16" MBP and am very happy with the projector output performance... BUT the monitor previews can't keep up and each seems to be well below 30fps, meaning i have to mix off the main projected screen and not the preview monitors (which i'd prefer).

I've tried adjusting each monitors "fps limit" between 0 and 30 but doesn't seems to make any difference. Am hoping that when this bug is fixed, if i set the fps limit = 0 then it will display at max fps my system can support (and will match the projector output).

Am forever thankful Isadora is in my life, Mr J

@jfg awesome, thankyou  🙈 I was searching for "get..." "cycle" "load" "fps" etc!
